I ran the data through excel and made a graph for Corporate profits as a percent of National income:
It does look a little clearer in this regard. I guess the increase in profits have coincided with the bailouts/QE’s/OperationTwist.
The average is 6.97%. Since 2005, its been 10% or higher except for ’08 thru mid-’09. The last four quarters is the highest its ever been as a percent of National Income.
